Embodiment
The invention provides a kind of for the connection locking device between two mutual sheathed tubing strings, this connection locking device holds by anchor ear portion the tubing string that is locked tightly, during locking state, the area that this connection locking device extrudes the tubing string that is locked is larger, locks more firm.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 2, a kind of structural representation connecting locking device that Fig. 2 provides for the embodiment of the present invention.The connection locking device that the present embodiment provides, for the locking between two mutual sheathed tubing strings, comprise anchor ear portion 1 and location division 2 two parts, described anchor ear portion 1 is set in first and treats on locking tube column outer wall, described location division 2 is connected with described anchor ear portion 1, for described anchor ear portion 1 location and installation being waited to lock tubing string in described second.When described anchor ear portion 1 holds described first tightly in time locking tubing string, described first treats cannot produce relative displacement between locking tubing string and described anchor ear portion 1, and described anchor ear portion 1 treats on locking tubing string by described location division 2 location and installation in described second, therefore described first treat that locking tubing string and described second is waited to lock between tubing string and also cannot be produced relative displacement, mutually cannot stretch by pull between two tubing strings, namely achieve two and wait to lock the locking between tubing string.On the contrary, when described anchor ear portion 1 loosens described first in time locking tubing string, described first waits to lock tubing string can move and realize and described second wait to lock mutual pull between tubing string, stretch in described anchor ear portion.The present invention utilize hold tightly, hooping structure that squish area is larger, achieve the locking between two mutually sheathed tubing strings with the structural principle of concision and compact more, easy to use, be also convenient to manufacture.
Please refer to Fig. 3-Fig. 6, a kind of structural representation connected when locking device is in locking state that Fig. 3 provides for the embodiment of the present invention, the A-A face cutaway view that Fig. 4 is structural representation shown in Fig. 3, a kind of structural representation connected when locking device is in relaxation state that Fig. 5 provides for the embodiment of the present invention, the B-B face cutaway view that Fig. 6 is structural representation shown in Fig. 5.
In the connection locking device that the invention described above embodiment provides, in order to enable the operation of holding tightly, loosening in described anchor ear portion more simple and convenient, anchor ear portion 1 specifically can comprise: sleeve part 101, first locking end 102, second locking end 103, cam part 3 and check lock lever 4.
Described sleeve part 101 is set in described first and treats on locking tube column outer wall; Described first locking end 102 and the second locking end 103 are extended along described sleeve part 101; Described check lock lever 4 comprises connecting rod 401, be arranged on the limit shaft 402 of one end of described connecting rod 401, and be arranged on the other end of described connecting rod 401, for carrying out spacing positive stop end 403 to described second locking end 103, described cam part 3 can be rotated around described limit shaft 402, and described cam part 3 matches with the outer face of described first locking end 102.
Its operation principle is as follows: arrange because described cam part 3 matches with the outer face of described first locking end 102, when rotating described cam part 3, relative distance between described first locking end 102 to affiliated second locking end 103 will be corresponding increase or diminish, thus realize described sleeve part 101 loosen or hold tightly described first wait lock tubing string.In order to more be convenient to realize rotating operation to described cam part 3, spanner 301 can be set in described cam part 3, by pulling the rotating operation that described spanner 301 realizes described cam part 3, more simple and practical.Certainly, also not necessarily spanner 301 must be set at this, arrange some other structure that can realize carrying out rotating operation to described cam part 3 also can, be not described in detail at this.
In order to ensure that described sleeve part 101 can realize waiting to lock holding tightly or loosening of tubing string to described first, sleeve part 101 need use elastomeric material to make, but due to material restriction, after the certain number of times of use, its deformation recovery capability may decrease, and then cause when carrying out loosening operation, sleeve part 101 cannot return to relaxation state completely from locking state, affect its result of use, in order to avoid the generation of this kind of situation as far as possible, in the connection locking device that the invention described above embodiment provides, spring 6 can be set between described first locking end 102 and the second locking end 103, utilize the auxiliary restitution of spring 6, ensure that described sleeve part can revert to relaxation state from locking state better.More electedly, between two locking ends, dislocation is deflected in order to prevent described spring 6, affect result of use, spring card slot 5 can also be oppositely arranged on the inner face of the inner face of described first locking end 102 and described second locking end 103, and described spring 6 is arranged in described spring card slot 5.
Please refer to Fig. 7, Fig. 8, Figure 11, wherein, the decomposition texture schematic diagram of a kind of microphone holder that Fig. 7 provides for the embodiment of the present invention, the structural representation of a kind of spanner that Fig. 8 provides for the embodiment of the present invention, the structural representation of a kind of lateral connector that Fig. 9 provides for the embodiment of the present invention, Figure 10 is the enlarged diagram of C part in Fig. 7, and Figure 11 is the enlarged diagram of D part in Fig. 7.
As shown in Figure 7, a kind of microphone holder that the embodiment of the present invention provides, comprises base 7, stay pipe 8, longitudinal connector 10.On the base 7 of described stay pipe 8 location and installation in location and installation in microphone holder, described stay pipe 8 comprises first stay pipe 801 and second stay pipe 802 two parts, and described first stay pipe 801 and described second stay pipe 802 are by the mutual sheathed connection of described longitudinal connector 10.Described first stay pipe 801 is the stay pipe that in two stay pipes, internal diameter is larger, namely described second stay pipe 802 is set in described first stay pipe 802, any one connection locking device that described longitudinal connector 10 provides for the invention described above embodiment, and location division 2 location and installation of described longitudinal connector is on described first stay pipe 801, anchor ear portion 1 is set on the outer wall of described second stay pipe 802.The locking between two stay pipes can be realized by described longitudinal connector and loosen, thus mutual pull or locking positioning can be completed between two tubing strings, in use procedure, as required, user selectively by the second locking tubing string 802 described in pull, and can lock in place, thus regulates the height of described microphone holder, flexibly simple to operate, convenient and reliable.
Similarly, in the microphone holder that the invention described above provides, the location division 2 of its longitudinal connector 10 also can be set to hooping structure, further facilitates and positions operation to it, and the dismantled and assembled operation of described longitudinal connector 10 can also be realized, enhance the flexibility that it uses.
